SPECIFICATION OF CHIP ON TOP SMD TYPE LED
Chip on Top SMD LED Light Source
Model: XT1511-RGBX-XX
These SMD LEDs are packaged in the industry standard CLPP6 package. These high-reliability
and high-brightness LEDs are designed to work in a wide range of environmental conditions and
are ideally suited for use in illumination applications. Their wide viewing angle makes these LEDs
ideally suited for channel letter, or general backlighting and illumination applications. The flat top
emitting surface makes it easy for these LEDs to mate with light pipes. All components are
produced by packing high-performance LED chips and silicon resin with proprietary phosphors.
1. Features and Benefits

. Higher heat conductivity for better thermal management
. Provide variable and innovative array LED layout designs and combinations
. Reduce the initial development cost and time
. High lumen-performance per dollar cost
. Lead free reflow solder compatible with RoHS compliant
2. Applications
. Light Strip
. Channel Letter
. Backlight
3. Dimensions and Materials
. Dimensions: 5.5 mm x 5.0 mm x 1.6 mm
. Packages: Top SMD
. Capsulated Resin: Silicone Resin with Aluminate Phosphor
. Electrodes: Ag Plating
. Chips: Total 4 chips packed in a cavity

The reel pack is applied in SMD LED. The LEDs are packed in cardboard boxes after packaging
in normal or anti-electrostatic bags. cardboard boxes will be used to protect the LEDs from
mechanical shocks during transportation. The boxes are not water resistant and therefore must
be kept away from water and moisture.

TOP SMD LED Application Notes
1. Features
The Purposes of making the customers and users to have a clear understanding on the ways how to use the
LED.
2. Description
Generally. The LED can be used the same way as other general purposed semiconductors. When using the TOP SMD
LED, the following precautions must be taken to protect the LED.
3Cautions
3.1. Dust & Cleaning
This emitter has a silicone surface, There are many benefits to the silicone surface in terms of optical properties and improved
reliability. However, silicone is a softer material and prone to attract dust. While a minimal amount of dust and debris on the LED
will not cause significant reduction in illumination, steps should be taken to keep the emitter free of dust.
These include keeping the LEDs in the manufacturer’s package prior to assembly and storing assemblies in an
enclosed area after installing the emitters.
Surface condition of this device may change when organic solvents such as trichloroethylene or acetone were applied.
Avoid using organic solvent, it is recommended that isopropyl be used as a solvent for cleaning the LEDs. When using
other solvents, it should be confirmed beforehand whether the solvents will dissolve the package and the resin of not.
Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence as ultrasonic cleaning on the LEDs
depends on factors such as ultrasonic power. Baking time and assembled condition. Before cleaning, a pre-test should be
done to confirm whether any damage to the LEDs will occur.
3.2. Moisture Proof Package
In order to avoid the absorption of moisture during transportation and storage, LED are packed in the aluminum envelop, A
desiccant is included in the aluminum envelop as it absorbs moisture. When moisture is absorbed into the AMT package it
may vaporize and expand during soldering. There is a possibility that this can cause exfoliation of the contacts and
damage to the optical characteristics of the LEDs. For this reason, the moisture proof package is used to keep moisture to
a minimum in the package.
3.3. Storage
In order to avoid the absorption of moisture, It is recommended to store SMD LED (in bulk or taped) in the dry box (or
the desiccator ) with a desiccant, Otherwise to store them in the following environment as recommended.
a. Temperature: 5℃~30℃ b. Humidity: 60% RH Max
It is recommended to solder the LED as soon as possible after unpacking the aluminum envelop, But in case that the
LED have to be left unused after unpacking envelop again is requested.
The LED should be soldering within 1 hours after opening the package. If
baking is required, A baking treatment should be performed as follows:
70℃±5℃ for more than 24 hours.

3.4. Reflow Soldering Characteristics
In testing, Has found XT1511 LEDs to be compatible with JEDEC J-STD-020C,using the parameters listed below. As a
general guideline recommends that users follow the recommended soldering profile provided by the manufacturer of
solder paste used.
Note that this general guideline is offered as a starting point and may require adjustment for certain PCB designs
and Configurations of reflow soldering equipment.

3.5. Heat Generation
Thermal design of the end product is of paramount importance. Please consider the heat generation of
the LED when making the system design. The coefficient of temperature increase per input electric
power is affected by the thermal resistance of the circuit board and density of LED placement on the
board, as well as components. It is necessary to avoid in tense heat generation and operate within the
maximum rating given in this specification. The operating current should be decided after considering
the ambient maximum temperature of LEDs
3.6. Electrostatic Discharge & Surge Current
Electrostatic discharge (ESD) or surge current (EOS) may damage LED.
Precautions such as ESD wrist strap, ESD shoe strap or antistatic gloves must be worn whenever
handling of LED. All devices, equipment and machinery must be properly grounded.
It is recommended to per form electrical test to screen out ESD failures at final inspection. It is
important to eliminate the possibility of surge current during circuitry design.
3.7. Other
Can not take any responsibility for any trouble that are caused by using the LEDs at conditions
exceeding our specifications.
These LEDs are designed and manufactured for standard applications such as electric home
appliances, communication equipment, office equipment, electronic equipment and so on.
It is recommended to consult us in advance if user’s application requires any particular quality or
reliability which concerns human life. Examples would be medical equipment, aerospace applications,
traffic signals, safety system equipment and so on.
Care must be taken to ensure that the reverse voltage will not exceed the absolute maximum rating
when using the LEDs with matrix drive.
The LED light output is strong enough to injure human eyes. Precautions must be taken to prevent
looking directly at the LEDs with unaided eyes for more than a few seconds.
The formal specification must be exchanged and signed by both parties before large volume purchase
begins. The appearance and specifications of the product may be modified for improvement without
notice.
